1. Unscrew the flat-head screw that tightens the clamp around the air intake tubing that connects directly to the throttle body on the right-hand ( driver ) side of the hood.

2. Unscrew the flat head screw that tightens the clamp at the other end of the above mentioned piece of tubing, it is actually a part of the next section of tubing but you will be pulling out the closer piece.

3. Remove the air intake tubing section from the throttle body and the second section of tubing.

4. Remove the fuel line that attaches to the side of the throttle body by pressing a small clip on the bottom of the line toward ( I think? ) the throttle body and moving it to the side, this will release the locking mechanism and allow you to pull it away from the throttle body with ease, this shouldn't be a struggle and be sure to be careful with the line, as it is fairly fragile.

5. Remove 4 - 10mm bolts that secure the throttle body to the supercharger, and disconnect the wiring harness. The harness is a bit tricky, I recommend a small flat-head screwdriver or a small, angled pick.

6. Separate the throttle body from the supercharger slowly, and be careful not to rip or tear the gasket between the two.

7. The fitting on the throttle body that the fuel line connected to is linked to a small port inside the throttle body on the supercharger-side of the butterfly. Spraying some throttle body cleaner through the port will do most of the work that needs to be done. I recommend taking a wire brush and some of your throttle body cleaner and spraying out the inner wall of the throttle body, as it ( if yours is anything like mine ) will have likely built up some measure of grime that may either continue to clog the fuel port, reduce air flow, or constrict movement of the butterfly.

8. Once you have cleaned the throttle body to your approval, and made sure that the fuel port isn't clogged ( blow some air through it and make sure that it comes out the other side freely ), re-attach it in the reverse order mentioned above, and viola, your problem is fixed.

If anyone has any comments or things I might adjust in this post please let me know, and thanks again to whomever started this post, easy fix to an irritating problem. Much appreciated.

i went to a auto parts store and was about to buy the throttle body cleaner until i read the back of the can, it said do not use on cars that have superchargers, turbos, and so on. what brand did you guys use?

i just cleaned it this morning, man what a difference it made. i always had the problem of stalling the car at a light when the a/c was on, now it stays put when i come to a light, driving like that for a year and all it needed was to be cleaned, thats a year of frustration down the tube.

So when im cruising at about 50-55 and i throw it into neutral before a stop light and coast to the stop light, (the AC is on idk if that matters) and it dips from about 500-1300 ish rpm, means i need to clean the throttle body out? Should I just alert the stealership when i drop it off?

Wow, Im soo glad to help soo many people out here. When this problem first happened to me I was talking to a buddy and said "I sure hope someone in North America can post something on here how to fix this damn idle problem" and then a few days down the road we went through possible areas that could cause this and when we finally figured out that the tb was fairly gunky at only 8,000km on her I realized this was the problem, so we cleaned it and the rest is history. It def looks like my thread has helped thousands of people out which gives me such a great feeling of accomplishment for such a small fix.lol. Anyhow, just for you guys out there wondering about the tb cleaner that says not to use on supercharged engines, dont worry about this warning as the best way to clean the tb is to remove it from the vehicle itself. Its a very quick thing to do and this way you are able to clean it thoroughly rather than half assing this therefore you dont have to clean it as often. Also, catch tanks are a very good solution to help fix this as the can will collect most of the gunk that is making its way to the tb.

If you remove the TB from the SC it is fine. The warning is so you don't spray the TB cleaner into the SC.

Ok I tried, took me 30 min to clean the TB. Started it up, left it running for like 5min. Didn't fix the problem but thanks for the advice. It stills idles the same way and when I put the a/c it drops even lower. **** my life. Anyone know how to fix this.

It's like that when you are tuned, just get used to it, why do you think GM deleted the AC from it's stage 3 tune!

I have an AEM dryflow filter, so I didn't think this would help me much but I tried it anyways. Just got finished, and damned if my idle isn't back to it was the day I bought it off the showroom floor! Thank you! My tb wasn't as dirty as some of yours probably was, but still pretty gunky for only having 34k on her.

True that... A/C is going to be like that on any 4 banger, its alot of extra strain on these tiny motors.

I am having the same issue with my 07 SS. The problem was amplified by a stage 3 zzp kit I just installed. I tried cleaning the throttle body but no dice. I have a new throttle body arriving today. Hopefully that will fix the issue. Will advise as soon as I get the new one on.
